Use a syringe or a cotton ball dipped in the solution to drip several drops of the mixture you have chosen into the ear

Leave it for around ten to fifteen minutes with your head to one side

After this, have some tissue on hand to mop up any excess mixture and earwax that comes out of your ear

Never, ever insert cotton buds into the ear directly; you are likely to impact the earwax further and could damage the eardrum | Source

2. Use commercially available ear drops

You can buy ear drops to soften earwax from your pharmacy or chemist. These drops are specially made to soften and remove earwax and can be quite effective.

You use them in the same way as the mixtures that you make yourself.

3. Use a specially designed ear syringe

Many pharmacies also sell ear syringes that will allow you to squirt warm water into your ear to irrigate it and remove excess earwax.

These syringes have a specially designed head to avoid squirting high-pressure water into your ear and damaging your eardrum. Always use the syringe with the head provided and never use a regular syringe to clean out your ears.
